Eclipse Filter Cartridges - Eclipse 1 - 3-pack (G)

Each pre-assembled Rite-Size cartridge filters water through a double thick polyfiber pad which traps more dirt and debris, faster. The cartridge is packed with super-efficient pure Black Diamond Activated Carbon. It keeps working long after most carbons stop.

It's better than a bag! Just shake and rinse. The patented ribbed backing evenly distributes carbon for maximum water-to-carbon contact. No bypass, no "tea-bag" effect. Just crystal clear, crystal clean water.

For best results, change every two to four weeks. Three cartridges per bag. Designed specifically for the Marineland Eclipse power filters.
